- Calculate the BLAKE2 checksum for a file:
|
|
|
|
|
|
|
|
|
|
`b2sum {{filename1}}`
|
|
|
|
|
|
|
|
|
|
- Calculate BLAKE2 checksums for multiple files:
|
|
|
|
|
|
|
|
|
|
`b2sum {{filename1}} {{filename2}}`
|
|
|
|
|
|
|
|
|
|
- Read a file of BLAKE2 sums and filenames and verify all files have matching checksums:
|
|
|
|
|
|
|
|
|
|
`b2sum -c {{filename.b2}}`
|
